Database error (in General)

Trying to equip my last few items to see if I can top 22m pr but I get this.

The database rejected the transaction. Most likely you double-clicked on the Assign link. If this is the case, your assignments were made correctly.

You think its because there is too much of a difference between my mpr and pr?
Current pr is 21,885,514
Current mpr is 12,854,51
I know its not a nw problem as I'm only at 1.56B
What I'm trying to equip is only 22m nw and adds about 46K pr.

Anyone any ideas?

what are you trying to equip to which minion

I've tried a lot of different combinations but a ms+64 on uuyu

apparently i can't get to the bottom of this issue... i wish a NightStrike were here.
